produced by the Washington Department of Fish and Wildlife(WDFW), and fish distribution maps produced by the WDFW (SalmonScape), Pacific States Marine Fisheries Commission (StreamNet) and Washington Department of Natural Resources (DNR; Forest Practices Application Mapping Tool [FPAMT]) were also evaluated as part of this project review. One wetland and a Shoreline of the State (Silver Lake) were identified on the project site. Wetlands & Wildlife, Inc. delineated the boundaries of the on-site wetland and on-site Ordinary High Water Mark (OHWM) of Silver Lake using bright pink flagging labeled in sequential order in accordance with professional ecological industry standards. The delineation flags were then surveyed by BBA Land Surveying, LLC. After the delineation flags were located using this method, Wetlands & Wildlife, Inc. imported the flag location data into a computer-aided drawing (CAD) program to depict the delineated Critical Area and Shoreline boundaries in relation to the property boundaries and other existing site features. See the attached Map Sheet CA1.00 for reference. RESULTS AND FINDINGS OF CRITICAL AREAS EVALUATION Based on our site evaluations, there is one regulated wetland and a Shoreline of the State located on the subject parcels as shown on the attached Map Sheet CA1.00. No other regulated Critical Areas were determined to be located on or within 300 feet of the subject properties that would potentially affect the proposed development. Cowardin Classifications: According to the Cowardin System, as described in Classification of Wetlands and Deepwater Habitats of the United States, the classifications for the regulated wetland and Silver Lake follow: Wetland A: Palustrine, Scrub-Shrub, Broad-leaved Deciduous, Seasonally Flooded (PSSIC) Silver Lake: Lacustrine, Limnetic, Unconsolidated Bottom, Sand (L1 UB2) Everett Municipal Code Classifications: Per Chapter 19.37 of the EMC, the classifications for the regulated wetland and Silver Lake follow: Wetland A is located among the northeastern portions of the subject properties and extends off-site to the north of the subject properties. Per industry standards and City of Everett requirements, Wetland A was rated using the 2014 Washington State Wetland Rating System for Western Washington, (Ecology Publication No. 14-06-029, published October 2014). The subject wetland meets the outlined criteria for "Lake Fringe"wetland. Therefore, the hydrogeomorphic(HGM) class used to rate the wetland was a"Lake Fringe"wetland on the Wetland Rating Form. Using the Wetland Rating Form, Wetland A scored a total of 19 points (8 points for Water Quality Functions, 6 points for Hydrologic Functions, and 5 points for Habitat Functions) and is therefore considered a Category Ill wetland. The rating form is attached to this report for viewing. Per Table 37.2 shown in EMC section 19.37.110, Category Ill wetlands with low level of function for habitat (Habitat Functions score of 3-5) require a standard protective buffer width of 80 feet to be applied parallel to the wetland boundary without mitigation measures. Therefore, the standard buffer Wetlands& Wildlife, Inc.
